| As the digital mobile communication, Internet technology development, the network supporting the existing circuit-switched voice and video-based telephone services are also needed to support packet data exchange service. GPRS network is a GSM network-based wireless packet communication system to GSM system architecture, through the radio access network and core network equipment on both sides of new features and interface protocols, mobile packet service a means of communication.Now GSM system as have been upgraded to the GPRS network, GPRS network, but how to evaluate performance and user experience, is not a very effective means of measurement and evaluation. So GPRS network performance and service quality assessment has become a hot spot by operators discussed. On the GPRS network performance through the assessment of the network operator can guide the operation, maintenance, optimization, quality evaluation for wireless packet service analysis can address the needs of end users to develop new business, enhance the end-user group business experience, and Shi mobile Internet end-users to truly become the beneficiaries.How to evaluate network performance and service quality, the current generally use two methods, the first for the network device performance was evaluated using the OMC-R system (operation and maintenance system), this method usually only for equipment, difficult to assess the overall network the true performance and end-user perception, the second, for assessing the quality of group operations is based on drive test, fixed tests, users pay a return visit. These two methods are relatively one-sided reaction of the network performance and service quality, in order to scientifically assess the network and many branch offices of China Mobile Communication Co., Ltd. requested equipment providers a system to graphics and diagrams to show the performance and network quality of service for an accurate scientific assessment of GPRS network.In the GPRS wireless packet network, core network and wireless access networks have a very important interface-"Gb interfaces", wireless networking and connectivity play a carry packet core role, by analyzing the GPRS network interface, this is an important signaling process, collection and analysis of Gb interface control plane and user plane data, the GPRS network service quality and network performance evaluation, so that you can put aside the device itself, to achieve an objective evaluation of GPRS network performance and network quality of service provided. In order to meet the operators GPRS wireless packet network performance and service quality assessment method based on the GPRS network interface signaling data analysis methods, network performance of the GPRS network and service quality assessment, evaluation more scientific.As an evaluation system to achieve it, the system is based on network data analysis approach, using a database system using the method of data analysis, will analyze the obtained quality of network performance and business evaluation results to B/S architecture, and C/S architecture submitted to the operator customers to meet customer GPRS network assessment of the two previously mentioned requirements.Performance of GPRS wireless packet network and business system design and implementation of quality assessment of overall idea is based on GPRS wireless network operator business evaluation system, develop and interface to the collection decoding GB storage server software, database system for convenient use of the powerful analysis features of the collection The interface data analysis will analyze the results of the evaluation in two after the showing as to operator customers, the first approach by the WEB server, database extraction results of the assessment data to HTTP document format submitted, the second approach the customers specially prepared client application will submit the results of database queries. |
